Atmospheric sounding information obtainable from present-day advanced infrared systems

摘要

The current day set of advanced atmospheric sounders began with the Atmospheric InfraRed Sounder (AIRS) on the NASA EOS Aqua satellite in orbit since 2002, the Infrared Atmospheric Sounding Interferometer (IASI) aboard MetOp-A since 2006, and the Cross-track Infrared Sounder (CrIS) instrument aboard the Suomi NPP and JPSS series of satellites which began 28 October 2011. These ultra-spectral infrared satellite sensors provide global measurements for improving monitoring and predictive capability of the Earth-atmosphere system, enabling enhancements in weather prediction, climate monitoring, and environmental change detection. This presentation examines the thermodynamic state and trace species information obtainable from these satellite systems possessing different measurement and instrument characteristics.
